IMPROVEM ENT IN RAILWAY-CARS.

Specification forming part of Letters Patent No. 211,201, dated January 7, 1879; application iiled f May 7, 1878.

To all whom t may concern:

Be it known that I, JAMES M. WEYMOUTE, a resident of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a certain new and useful Improvement in Railway-Gars; and I do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed drawing, making a part of this specification.

This invention embraces several novel and highly-important features, the chief of which is an arrangement of traction-wheels, which are so applied to the frame of the vehicle as to overcome friction, and hence enable the same to be drawn or propelled with an ex-- to the accompanying drawing, whereon Figure l represents a side elevation; Fig. 2, a view from the under side. Fig. 3 represents a means by which the driving-power may be applied tothe wheels, and Fig. 4 a modiication of the traction-wheels.

The frame Ais provided with boxed side.

frames, b b', in which operate the tractionwheels c. These are constructed in sets of seven or any other odd number, and are connected by a pair of side chains, d, the pins of which serve as journals therefor. These wheels are made to operate around a central bearing, c, the latter of a circular, oval, or attened form. That shown in Figs. land 3 is deemed preferable, for the reason that it requires aless height of frame.

The bearings e are provided on each side with. flanges f, in order to insure the `working of the wheels in a direct line. Each pair of links are connected by a cross bar, i, which serves as a scraper for removing any dirt that may by chance be taken up by the Wheels.

The sides b and b are provided with vertical openings, in which are fitted steel or other springs, g, the lower ends of which are connected with pins or bolts h, that are fitted in the bearings c and washers or side plates, lc, as shown, so that the weight of the whole apparatus may be upon the peripheries of the wheels, which in their rolling progressive movement are continually presenting new bearing-surfaces.

The ilanged wheels l are each provided with a central pin, the ends of which operate in slotted bearings m, that are secured to the inside of the box-frame pieces b, as shown, so as to operate against the inner edges ofithe rails, and thus serve to prevent the apparatus from running o' the track. These wheels should be providedwith levers, so that they may be raised or lowered at pleasure, and additional wheels can be applied upon the outer sides of the frames, by which arrangement the car can be guided onto a side track simply by raising the inner wheels, so as to clear the switch, and by lowering those on the side where the branch track is located.

The brake consists of a pair of eccentrics, N N', that are keyed or otherwise secured to a shaft, O. This shaft is provided with a crank, p, which is connected with an operatinglever (shown in dotted lines at q) by means of a rod, c, and through which the eccentrics are made to operate on the face of the rails whenever it is required to stop the car.

This car may be propelled by animal-power or a motive power may be placed on the body of the car, and the power transmitted through a cog-wheel, E, which,for this purpose, is made to engage in teeth that are cut in the outer edges of the links d, as shown.

It is intended to represent by Fig. 4 that should a circular bearing be employed, it will be necessary to incase the wheels c in a lnetal ring, a', as otherwise the said wheels would represent the outer ends of so many spokes, and in consequence thereof this form of bearing would, wit-hout the ring, be utterly impracticable. In this case flanges may be applied to the rings a', thus dispensing with the independent flange-wheels l.

Having described my invention, what I claim as new, and desire to secure by LettersPatent,l In testimony WhereofI have hereunto signed ismy name,
